Optical Spectroscopy of Distant Red Galaxies
Stijn Wuyts, Pieter G. van Dokkum, Marijn Franx +4
We present optical spectroscopic follow-up of a sample of Distant Red Galaxies (DRGs) with K < 22.5 (Vega), selected by J-K > 2.3, in the Hubble Deep Field South, the MS 1054-03 fi…
Discriminating Between the Physical Processes that Drive Spheroid Size Evolution
Philip F. Hopkins, Kevin Bundy, Lars Hernquist +2
Massive galaxies at high-z have smaller effective radii than those today, but similar central densities. Their size growth therefore relates primarily to the evolving abundance of…
The size-star formation relation of massive galaxies at 1.5<z<2.5
S. Toft, M. Franx, P. G. van Dokkum +4
We study the relation between size and star formation activity in a complete sample of 225 massive (M > 5 x 10^10 Msun) galaxies at 1.5<z<2.5, selected from the FIREWORKS UV-IR cat…
Color Distributions, Number and Mass Densities of Massive Galaxies at 1.5 < z < 3: Comparing Observations with Merger Simulations
Stijn Wuyts, Marijn Franx, Thomas J. Cox +9
We present a comparison between the observed color distribution, number and mass density of massive galaxies at 1.5 < z < 3 and a model by Hopkins et al. that relates the quasar an…
A Public, K-Selected, Optical-to-Near-Infrared Catalog of the Extended Chandra Deep Field South (ECDFS) from the MUltiwavelength Survey by Yale-Chile (MUSYC)
Edward N Taylor, Marijn Franx, Pieter G van Dokkum +20
We present a new K-selected, optical-to-near-infrared photometric catalog of the Extended Chandra Deep Field South (ECDFS), making it publicly available to the astronomical communi…
Recovering Stellar Population Properties and Redshifts from Broad-Band Photometry of Simulated Galaxies: Lessons for SED Modeling
Stijn Wuyts, Marijn Franx, Thomas J. Cox +4
We present a detailed analysis of our ability to determine stellar masses, ages, reddening and extinction values, and star formation rates of high-redshift galaxies by modeling bro…
